Abstract

A digital broadcast receiving system and a method for controlling the same are disclosed. The method includes the steps of receiving a broadcast signal having mobile service data and main service data multiplexed therein, extracting transmission parameter channel (TPC) signaling information and fast information channel (FIC) signaling information from a data group within the received mobile service data, wherein the FIC signaling information includes a current/next (C/N) indicator, and wherein the TPC signaling information includes FIC version information, and detecting ensemble configuration information of a current MH frame.

Claims

exact text as granted — not AI-modified
1. A method of processing broadcast data in a broadcast transmitter, the method comprising:
 performing, by a Reed Solomon (RS) encoder, RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data; 
 inserting the RS-encoded and CRC-encoded mobile service data in a group; 
 inserting fast information channel (FIC) data and transmission parameter channel (TPC) data in a signaling area of the group, wherein the FIC data includes a current and next (C/N) indicator field indicating whether the FIC data is applicable to a mobile and handheld (M/H) frame in which it appears or a next mobile and handheld (M/H) frame, and wherein the TPC data includes FIC version information for indicating an update of the FIC data; and 
 transmitting a broadcast signal including the data group. 
 
   
   
     2. The method of  claim 1 , wherein the FIC data further includes cross layer information for mobile service acquisition. 
   
   
     3. The method of  claim 1 , wherein, when the C/N indicator is set to 1, the C/N indicator indicates that the FIC data is applicable to the next M/H frame. 
   
   
     4. The method of  claim 1 , wherein, when the C/N indicator is not set to 1, the C/N indicator indicates that the FIC data is applicable to the current M/H frame. 
   
   
     5. The method of  claim 1 , the FIC data further includes error indication information indicating whether the FIC data contains an error. 
   
   
     6. The method of  claim 1 , further comprising:
 inserting regularly spaced known data sequences which are known by transmitting and receiving sides in advance in the group. 
 
   
   
     7. The method of  claim 6 , wherein at least two of the known data sequences differ from each other in length. 
   
   
     8. A broadcast transmitter comprising:
 an RS frame encoder for encoding means for performing RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data; 
 an inserting means for inserting the RS-encoded and CRC-encoded mobile service data, fast information channel (FIC) data and transmission parameter channel (TPC) data in a group, wherein the FIC data includes a current and next (C/N) indicator field indicating whether the FIC data is applicable to a mobile and handheld (M/H) frame in which it appears or a next mobile and handheld (M/H) frame, and wherein the TPC data includes FIC version information for indicating an update of the FIC data; and 
 a transmitting means for transmitting a broadcast signal including the group. 
 
   
   
     9. The broadcast transmitter of  claim 8 , wherein the FIC data further includes cross layer information for mobile service acquisition. 
   
   
     10. The broadcast transmitter of  claim 8 , wherein, when the C/N indicator is set to 1, the C/N indicator indicates that the FIC data is applicable to the next M/H frame. 
   
   
     11. The broadcast transmitter of  claim 8 , wherein, when the C/N indicator is not set to 1, the C/N indicator indicates that the FIC data is applicable to the current M/H frame. 
   
   
     12. The broadcast transmitter of  claim 8 , the FIC data further includes error indication information indicating whether the FIC data contains an error. 
   
   
     13. The broadcast transmitter of  claim 8 , wherein the inserting means further inserts regularly spaced known data sequences in the group.
